My AMD Radeon RX 6600M has a code 43 driver error

[zonster]

My laptop has been acting a little sluggish when watching Youtube, so i updated my computer via windows update and BIOS update. I restarted my computer but that didnt make a difference. It took some time but i finally found whats wrong in the drivers and printers section. When i clicked my laptop it showed this.

Then i navigated and saw my AMD driver had the error and it shows this

I then looked at the events and theres errors back to 2014, so i guess i hadn't fixed it since then via updates. These are the type of errors below.

 

Would like some assistance in fixing the error, hoping its not a ruined graphics driver that would require a laptop replacement. Thank you in advance!

Your laptop still under warranty? 

Do this:

1. Download the latest AMD software version from AMD driver site for rx6600m
2. Pause windows update and Download ddu (display driver uninstaller) and run it in safe mode
3. Select device type GPU and then brand "AMD"
4. Click on clean and restart.
5. Now, install and software or driver that you downloaded. After installation, check if code 43 remains or disappear.

I dont have warranty but followed your steps. I downloaded the DDU and rebooting in safe mode and was installing my AMD again afterwards when i came across this error.

So it looks like the AMD is not installing for some reason, is there a way to get it to download correctly? Thank you for your response!

This happens after you install and software and when you try to open? Doesn't device manager show same? Which CPU/GPU you have?

No it happened during download, i tried again but this time i chose the option to clear the existing version and did accept and install instead of accept and express install and i didnt get the message again. However checking the device manager it still shows code 43 after everything. These are my specs in my 'about this device':

Processor AMD Ryzen 7 5800H with Radeon Graphics (3.20 GHz)
Installed RAM 16.0 GB (15.3 GB usable)
System type 64-bit operating system, x64-based processor
Edition Windows 11 Home
Version 25H2

I checked the events again after installing successfully and these are the errors i got

May be a error because your laptop have two GPUS and both need seperate driver. Follow these steps:

Before starting, create two folders on your Desktop: one main folder for all drivers files, and a separate folder only for the AMD Adrenalin iGPU (Ryzen 7 5800H) installer to keep it clearly separated and avoid confusion during installation.

Here are the driver files:
I. AMD Adrenalin Software (iGPU – Ryzen 7 5800H):
Visit AMD Driver page → Processors → Ryzen → 5000 Series → 5800H → Submit → Download. (Save this is seperate place)

II. AMD Adrenalin (dGPU – RX 6600M):
AMD Driver page → Graphics → Radeon RX → 6000 Series → RX 6500M → Submit → Download

III. AMD Laptop Chipset Driver:
AMD Driver page → Chipsets → Laptop Chipsets → AMD Ryzen™ and Athlon™ Mobile (Chipsets) → Submit → Download

IV. Download and install 7-zip
https://www.7-zip.org/

V. Downlaod DDU (Display Driver Uninstaller)
https://www.guru3d.com/files-details/display-driver-uninstaller-download.html

VI. Download Microsoft Show/Hide Updates tool (wushowhide.diagcab)-
https://download.microsoft.com/download/f/2/2/f22d5fdb-59cd-4275-8c95-1be17bf70b21/wushowhide.diagca...

• Now pause Windows Update and disconnect Wi-Fi or Ethernet, whichever you use, and don't connect or resume updates until I say.

• Boot into Safe Mode, then extract DDU and open it. Select Device type GPU, then select AMD and click on Clean and Restart. Wait for completion until DDU uninstalls the driver properly.

• After restart, right-click on the Windows icon, then click on Installed Apps. From here, find and uninstall any chipset driver software. If it's not available, then you never installed the chipset driver manually and those users skip this point. After uninstalling the chipset driver software, click on Restart.

• After restart, Open the folder where you saved the AMD iGPU Adrenalin installer, right-click it → Open with 7-Zip, then go to Packages → Drivers and extract only the “Display” folder to your Desktop (do not extract the full installer).

• Now open Device Manager → Expand Display adapters → right-click Microsoft Basic Display Adapter→ Update driver → Browse my computer for drivers → Browse → select the extracted Display folder on Desktop → Next and wait for installation to complete. Close device manager when done

• Now, we will install the dGPU driver normally using software. Open the folder where your remaining downloaded files are located. Double-click the AMD Adrenalin (dGPU) installer, follow the on-screen instructions to install it (like Accept → Installation Type: Full Install → Install) and let it finish. Once completed, close the installer and AMD Software if it opens automatically, then restart your laptop.

• Next, install the AMD Chipset software normally. Double-click the installer, follow the on-screen instructions, keep all devices/drivers selected, and click Install. Let it complete and restart your laptop when done.

• Now after restart, connect to Wi-Fi, then immediately open the Microsoft update hide tool (wushowhide.diagcab) from the folder when your save files. Click on "Hide Update," then select every update whose name starts with "AMD" or "Advanced Micro Devices," etc. Make sure to select all updates labeled as "AMD" or "Advanced Micro."

(If you don't see these updates in the windows hide tool then you can skip this part as windows is not overwriting the driver in your system so there's nothing to hide.)

• After selecting all, click Next. All updates you selected will be shown as fixed on the next screen. If it shows, then you have successfully done this.

• Now restart and Windows will not overwrite AMD drivers anymore. You can now resume the Windows Update.

• Check if issue got fixed
